A crew of artists found a new way to ‘clean up’ graffiti in a public place by simply erasing a car and dumpster from a street in Russia using the old familiar Photoshop transparency pattern. Called CTRL+X, the piece was created as part of the Stenograffia street art festival, and carrying it out was simple – if a little bit time consuming. Before they got started, the surfaces were covered in tags in all shades of the rainbow, and they had to paint everything a matte light gray as a base.

After dark, they set up a projector so they could trace the Photoshop checkerboard pattern from the perspective point from which the scene would be viewed by the public, so it’s angled just right. They used pencil to mark the lines, and then taped off the squares that needed to be painted a darker gray.

The end result is a pretty fun optical illusion that’s probably only effective for people who are used to working in Photoshop. Check out lots of behind-the-scenes photos on the Stenograffia Facebook page.
